Question

please please can any one help me please​

Answer 1

Answer:

Step-by-step explanation:

perimeter =8+21+21=50cm

equal sides length=21

it cant be 8 because 8+8<21

this triangle is not possible

so equal side length is 21cm

Answer 2

Answer:

There could be two answers to this question. 37cm or 50cm

Step-by-step explanation:

Since we have an isosceles triangle, we know that there are 2 equal sides

Thus, either the missing side has length 8 to give us a 8-8-21 triangle,

or

the missing side has length 21 to give us a 8-21-21 triangle.

The perimeter of a 8-8-21 triangle

8 + 8+ 21 = 37 cm

The perimeter of a 8-21-21 triangle

8 + 21+ 21 = 50 cm

hope it helps!
